SMOKING PIPE.

Application filed June 12, 1925. Serial No. 36,731.

This invention relates to improvements in smoking pipes.

The primary object of the invention resides in a smoking pipe in which is embodied a means for delaying the smoke in its passage from the bowl of the pipe to the stem, when the pipe is in use, by first causing the same to travel in a direction away from the mouth piece of the stem and thence in a reverse direction toward the mouth piece whereby to cool the smoke prior to reaching themouth of the smoker.

Another object of the invention is to provide a recess within the pipe in which is inserted a member adapted to divide the recess into a plurality of communicating chambers through which the smoke is adapted to pass in its travel from the bowl to the stem to cool the smoke and to trap the saliva, and wherein the recess is scraped clean of any moisture or dirt which may collect therein upon the withdrawal of the member.

l/Vith these and other objects in view, the invention resides in certain novel construction and combination and arrangement of parts, the essential features of which are hereinafter fully described, are particularly pointed out in the appended claims, and are illustrated in the accompanying drawing, in which Fig'ure.1 is a longitudinal sectional view through my improved pipe.

Figure 2 is a transverse sectional view on the line 2-2 of Figure 1.

Figure 3 is a detail crspective view of the removable filter mem )er.

Figure 4 is a vertical sectional view of a slight modification.

Figure 5 is a similar view of a further modified form.

Referring more particularly to the drawing, and especially to Figures 1 to 3 inclusive, the reference numeral designates my improved smoking pipe in its entirety and which includes the usual bowl 11 and stem 12. An elongated recess 13 is formed in the stem below the bowl and opens at the front of the pipe. A. bore 14 communicates with the rear, of the recess and leads to the mouth pieceof the stem, but said bore is not in axial alignment throughout its length but it provided with an offset Passage 15.

The recess 13 receives a metallic sleeve 16 which serves as a lining for the walls of the recess and is frictionally held therein by the walls. A duct 17 connects the bowl 11 with the interior of the sleeve and enters the sleeve adjacent the rear end thereof.

Insertable in the open end of the recess is a filter member 18, which includes spaced sets of disks 19 and 19' which are connected by a longitudinal wall 20 which divides the surfaces of the disk int/o halves. Each disk 19 is formed with an opening 21 on opposite sides of the wall, while the disks 19' are only provided with a single opening 22 disposed on opposite sides of the wall. The wall 20 is formed integral with a screw cap 23, threaded in the open end of the recess 13 for removably supporting the filter member within the IQCQS-T. It will be seen that when the filter member is in position within the recess, the said recess is divided into a plurality of upper chambers 24 and a plurality of lower chambers 25. The upper and lower end chambers have communication with each other through apertures 26 provided in the wall 20.

In use, the smoke is drawn through the duct 17 into the upper chamber 24 between the sets of disks 19 and 19. thence through the openings 21 in the disks 19, down through the communicating opening 26 and into the front lower chamber 25, through the chambers to the rear lower chamber and then to the upper end chamber 24 through the opening 22 and through the bore 14 to the mouth piece of the stem. In Figure 1 of the drawing, I have shown arrows to indicate the direction of the travel of the smoke in its passage from the bowl to the mouth piece and it will be noted on the draw the smoke travels in a direction away from the mouth piece and thence in a reverse direction toward the mouth piece. This action serves to delay the smoke sutficiently long enough to cool the same and to trap any nicotine and saliva before entering the bore of the stem thus keeping the bore clear and dry at all times.

The saliva and the like may be quickly removed from the pipe as the occasion requires by unscrewing the cap and withdrawing the filter member which causes the disks to sera e the walls of the sleeve clean.

In Figure 4 of the drawing, T have shown a slightly modified form of filter member designated by the reference numeral 27 and which includes a tube 28 supporting spaced disks 29. The duct 17' leading from the bowl enters the space between the disks and passes through an opening 30 in the rear end disk 29 and thence enters the front end of the tube where it passes to the bore 14 in tion, it is obvious that many of the details the stem. A cap 31 is threaded into the recess but is not integral with the filter member as shown in the preferred form. The sediment or saliva and tobacco is collected between the disks and is automatically removed upon the withdrawal of the member from the recess.

In Figure 5 of the drawing, I have shown a further modification which is similar to the other forms of my invention but in which the tube 27 extends into the passage 14 in the stem. The tube supports spaced disks 32 between which is interposed a disk 33 having an opening 34 therein. The duct 17 leading from the bowl enters between the rear disk 32 and the disk 33 so that the smoke enters the chamber defined by these disks and then passes through the opening 34 in the tube between the front end disk 32 and disk 33. The stem 11 in this form is constructed with a removable mouthpiece section 35 and when the section is removed, the filter member will move with it, thus cleaning the walls of the recess in which the member is inserted.

In all the forms of my invention, the same principle is involved, that is, the feature of causing the smoke to more in opposite directions before reaching the end of the mouthpiece and for filtering the smoke in its travel.

While I have described what I deem to be the most desirable embodiment of my invenmay be varied without in any way departmg from the spirit of my invention, and I therefore do not limit myself to the exact details of construction, herein set forth nor to anything less than the whole of my invention limited only by the appended claims.

What is claimed as new is 1. A smoking pipe comprising a bowl, a stem, a recess provided in .said stem, and a removable member seated within said recess for causing smoke to travel in a direction away from the mouthpiece of the stem after leaving the bowl and prior to its entrance into the stem, said member including disks for scraping engagement with the walls of said recess upon the removal of the same.

*2. A smoking pipe comprising a bowl, a stem, a recess formed in said stem, a duct leading from said bowl to said recess, a bore leading from said recess to the free end of said stem, and a removable member having spaced disks fitted within said recess and provided with suitable openings for causing snzoke to travel in a direction away from said bore and thence in a direction toward said bore, said duct entering said recess intcrmediate certain of said disks.

In testimony whereof I have afiixed my signature.
